This is the most widespread wood-warbler in North America, often mistaken for a "wild canary". Its scientific name is Dendroica petechia (now Setophaga petechia). Dendroica is latin for "tree-dwelling", petechia refers to the red streaks on the breast of the male. Believe it or not petechia is actually a medical term for a condition similar to red rashes! (The new genus setophaga means insect-eating).
